According to a demographic study by Washington DC headquartered Pew Research Center, about 1.4 billion or 15% of the world's population will be Hindu in 2050.
This illustrates the possibilities that the worldwide Hindu population is estimated to rise by 34%, essentially keeping pace with the overall population growth.
Surveys suggest that Hindu fertility (2.4 per woman) is similar to the global average (2.5). However, this is lower than Muslim and Christian fertility, yet higher than Jewish and Buddhist. Further on, approximately 260,000 people will switch to Hinduism during 2010-2050, while about 250,000 will convert from Hinduism.
The study further reveals that the number of Hindus in Europe will double from just under 1.4 million (0.2% of Europe's population) to nearly 2.7 million (0.4%), primarily due to immigration. Additionally, the study also suggests that in the Middle East- North Africa, 0.6% population will be Hindu with migration and 0.3% without migration.
On one hand, the study has revealed the possible growth in the Hindu population; on the other hand, the study also suggests that the Muslim population in India will be on a rise as well. “Although India will continue to have a Hindu majority, by 2050 it is projected to have the world’s largest Muslim population, surpassing Indonesia. ”
